Hi Dai
Good Luck with this one 😀 and am plesed the net found you albeit Late :-S , I went on Zometa in 2010 after my 100 day BMB after Sct and had them for two years.
As for the Fatigue well I have sort of starting to put mine down::
1) being less active since diagnosis
2) Just plain old getting Older :-S Lol
Dai its Ok to go sideaways for a little bit but Onwards and Upwards Is the way to do it and you my friend are doing it 😎
Keep well and keep your eye on your temp, make sure you dont blame it on the Zometa alone :-/
Tom Onwards and Upwards
